Resolved pleskrestore: Perhaps /usr/local/psa/admin/bin/deployer application missing, has incorrect ...

I can't restore a single domain from a large local backup archive.

[root@server ~]# cd /tmp/backs/
[root@server backs]# ll
total 19291740
-rw-r--r-- 1 root root 19754732716 Nov 30 12:18 backup_1611250301.tar

You can view additional information in the log file located in /usr/local/psa/PMM/rsessions/20161130135404879 directory. This directory will be removed automatically after 30 days.

SELINUX is totally disabled, and I've run the tests I've seen aropund here:

root@server backs]# ls -la /usr/local/psa/admin/bin/deployer
lrwxrwxrwx 1 root root 15 Jul 19 15:26 /usr/local/psa/admin/bin/deployer -> ../sbin/wrapper
[root@server backs]# ls -la /usr/local/psa/admin/sbin/wrapper
---s--x--- 1 root psaadm 20104 Aug 26  2015 /usr/local/psa/admin/sbin/wrapper
[root@server backs]# ls -Z /usr/local/psa/admin/sbin/deployer
-rwxr-x--- root root ?                                /usr/local/psa/admin/sbin/deployer
[root@server backs]#
[root@server backs]# chcon -t bin_t /usr/local/psa/admin/sbin/deployer
chcon: can't apply partial context to unlabeled file `/usr/local/psa/admin/sbin/deployer'
[root@server backs]#

Anyone can help me please ?

Well, after lots of research the problem was server resources, the uncompression resources were reaching the RAM limit, so after upgrading RAM to 4G instead of 2G, the issue was fixed.

server kernel: [12353853.377135] Out of memory in UB 387: OOM killed process 2810 (deployer) score 0 vm:1776312kB, rss:984328kB, swap:324580kB
Nov 30 15:39:43 pymdemo xinetd[882]: START: ftp pid=6344 from=::ffff:181.161.21.81

The problem was the messages we were getting, so confusing and distant of the reality

Thanks everybody for your help !
